PROBLEM TO BE SOLVED: To shorten time of a correcting operation for the vertebrae (TB), to reduce a physical burden for a patient, and to reduce amounts of bleeding and a rate of bacterium infection. SOLUTION: This correcting device comprises a main rod 1 arranged in parallel to an axis of TB outside the human body, a central draw rod 3 for TB, whose shaft length is adjustable, in which a base part is mounted to the main rod 1 by a joint member 8, so that a tip part is oriented to TB, a plurality of side draw rods 4 for TB, whose shaft length is adjustable, in which base parts are mounted on both sides of the central draw bar 3 for TB of the main rod 1 by a joint member 10 in such a way that an interval to the central draw rod 3 can be adjusted, so that a rotation adjustable tip part is oriented to TB, and a vertebra fixture holding member 6 for TB formed in a reversed T shape in which a support arm 13 to support the vertebra fixture is protruded from a lower end of a connecting part 12 to both sides, and is mounted to tips of the central draw rod 3 for TB and the side draw rods 4 for TB by the connecting part 12 in such a way that oscillation can be adjusted, so that both ends of the support arm 13 can alternately be connected or separated to TB. By this, this device can be installed to TB through each vertebra fixture.
